Simulation high velocity impact of the steel bullet on the Ceramic-Epoxy panel in Abaqus

In this tutorial, the Simulation high velocity impact of the steel bullet on the Ceramic-Epoxy panel in Abaqus  has been investigated. The 3 alumina layers are modeled as three-dimensional solid part. The 2 epoxy glue layers are modeled as three-dimensional solid part. The steel bullet is modeled as a three-dimensional solid part. Because of the symmetry, on quarter of the whole model to reduce the time of the simulation is used. You can see a figures of the assembled part below

The Johnson-Cook plasticity and damage is selected for the steel material because this model can consider high-strain-rate deformation of many materials, including most metals. Abaqus/Explicit provides a dynamic failure model specifically for the Johnson-Cook plasticity model, which is suitable only for high-strain-rate deformation of metals. The data for the steel material is extracted from the reference paper. To model epoxy material, elastic data traction type couple with Maxs damage criterion is used. The epoxy is considered as a cohesive material by definition cohesive section. To model alumina behavior under high velocity impact, Abaqus recommends some material models which are available in Abaqus cae and some of them need to be written as codes. The dynamic explicit step with mass scale parameter is appropriate for this type of analysis. The general contact capability with friction as contact property is selected. The perfect contact is assume between the alumina and epoxy parts. The symmetry boundary is assigned to the symmetry zone and also initial velocity to the steel bullet. The mesh should be fine to obtain correct results

After the simulation, all results such as stress, strain, damage, failure, penetration, and … are available. You can see some figures for the results below
